Actually that is not fine for users that would play with legality testing off. (You might of course argue they should not do that.) An "Illegal move" command would make the GUI take the move that the engine refused back, in human-engine mode, so the GUI and engine stay in phase; "Error" would not do that.mkchan wrote:Still not making a distinction between an illegal move and an unrecognized command, it should be fine according to the site
Will upload WyldChess 1.1 with the change and some elo gain soon
Recommended is to use the usermove feature; then you will always know what are moves and what not. Even without it it is not so difficult, though: if the second character is a digit (or an @ sign if you also do piece drops), it is a move, otherwise a command keyword.
